1358 The Loongson 2F processor implements the MIPS III instruction set
1359 with many extensions.
1360
1361 Loongson2F have built-in DDR2 and PCIX controller. The PCIX controller
1362 have a similar programming interface with FPGA northbridge used in
1363 Loongson2E.

1479 Please make sure to pick the right CPU type. Linux/MIPS is not
1480 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1481 *not* work on R4000 machines and vice versa. However, since most
1482 of the supported machines have an R4000 (or similar) CPU, R4x00
1483 might be a safe bet. If the resulting kernel does not work,
1484 try to recompile with R3000.

1712 Addressing (XPA) on your MIPS32 core (such as P5600 series). The
1713 benefit is to increase physical addressing equal to or greater
1714 than 40 bits. Note that this has the side effect of turning on
1715 64-bit addressing which in turn makes the PTEs 64-bit in size.

1731 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1732 require workarounds. Without workarounds the system may hang
1733 unexpectedly. For more information please refer to the gas
1734 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1735
1736 Loongson 2F03 and later have fixed these issues and no workarounds
1737 are needed. The workarounds have no significant side effect on them
1738 but may decrease the performance of the system so this option should
1739 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1740 systems.
1741
1742 If unsure, please say Y.

2703 EF_MIPS_FP64 ELF header flag (typically built with -mfp64). On
2704 32-bit MIPS systems this support is at the cost of increasing the
2705 size and complexity of the compiled FPU emulator. Thus if you are
2706 running a MIPS32 system and know that none of your userland binaries
2707 will require 64-bit floating point, you may wish to reduce the size
2708 of your kernel & potentially improve FP emulation performance by
2709 saying N here.
